Although the pump of this embodiment is the air pump 26, the pump may be replaced with an electric pump.

As shown in FIG. 2, a safety valve 11 is housed in a valve chamber 3a of the safety valve device 3 connected to a rising portion above the water level pipe 2. The lower part of the safety valve 11
It is formed in the shape of an inverted truncated cone, and a tapered wall 12 is formed in the lower part of the valve chamber 3a corresponding to the shape of the lower part of the safety valve 11. A plurality of ribs 13 are provided on the inner surface of the tapered wall 12.
Are provided, and the lower side surface of the safety valve 11 is supported by these ribs 13.

The tapered wall 12 is provided with an inflow port 14 communicating with the water level pipe 2, and the upper part of the valve chamber 3a is provided with the communication part 4 at a predetermined gap from the upper surface of the safety valve 11. A communication port 10 is provided at an upper end of the communication section 4, and the safety valve device 3 and the discharge pipe 5 are connected.

The installation position of the safety valve device 3 is different from that of the discharge pipe 5.
1, the communication pipe 16 is provided between the safety valve device 3 and the communication port 10 of the discharge pipe 5 as shown by a two-dot chain line in FIG.

As shown in FIGS. 1 and 2, the discharge pipe 5 is provided with a water stop portion 6 and a bent portion 17 is formed on the discharge port 5 side of the water stop portion 6 of the discharge pipe 5. The tip faces the discharge port 23.

A spherical valve 9 is housed in the water stop portion 6. An annular valve seat 7 is provided at one end of the water stop portion 6 along the inner wall of the discharge pipe 5, and at the other end. , A standby recess 8 for the spherical valve 9 is provided. The communication port 10 is provided on the bottom surface of the water blocking portion 6 between the annular valve seat 7 and the recess 8, and the diameter of the communication port 10 is such that the spherical valve 9 is partially fitted. Note that, instead of the circular communication port 10 as described above, a plurality of slit-shaped communication ports 30 may be provided on the bottom surface of the water stop portion 6 as shown in FIG.

Further, the bottom surface of the water stop portion 6 between the annular valve seat 7 and the recess 8 is inclined so that the recess 8 side is lower than the annular valve seat 7 side. When the pot is slightly inclined to the discharge port 23 side, the spherical valve 9 at the position of the recess 8 causes the spherical valve 9 to be closed.
It is set so that it can move to the side.

A heater 27 for heating and keeping the temperature and a sensor 28 for detecting the temperature are attached to the bottom of the inner container 1, and a pot dedicated to keeping the heat in which the heater 27 and the sensor 28 are omitted is similar to the above. Can be provided with a water stop section.

When using the above pot, an appropriate amount of water or the like is put into the inner container 1, heated by the heater 27 to make hot water, and then the hot water is kept warm.

When the hot water in the inner container 1 is discharged, the push button 25 of the lid 24 is pushed in, and the hot water passes through the water level pipe 2, the safety valve device 3, and the liquid passage 15 in the discharge pipe 5. From the discharge port 23.

In this case, since the spherical valve 9 in the water stopping portion 6 is in a standby state in the recess 8, there is no hindrance for the hot water to pass through the liquid passage 15.

Next, when the pot is tilted toward the discharge port 23, the annular valve seat 7, which was initially higher than the recess 8, becomes lower than the recess 8 as the tilt angle of the pot increases. As a result, the spherical valve 9 located in the recess 8 moves toward the annular valve seat 7 (see the two-dot chain line in FIG. 3).

At this time, the spherical valve 9 first closes the communication port 10 to prevent an initial leak of hot water. When the inclination angle of the pot further increases, the spherical valve 9 moves to the annular valve seat 7 to close the discharge pipe 5 and completely prevent hot water from leaking when inclined to the discharge port 23 side.

As shown in FIG. 4, when a slit-shaped communication port 30 is provided on the lower surface of the discharge pipe 5, the spherical valve 9 is provided.
Moves to the side of the annular valve seat 7 in the same manner as described above, but moves directly to the annular valve seat 7 through the communication port 30, and the discharge pipe 5
To close.

When the pot is turned over, the safety valve 11 in the valve chamber 3a of the safety valve device 3 operates to open the communication port 10a.
Is closed (see a two-dot chain line in FIG. 2), so that the hot water in the inner container 1 can be prevented from leaking. In addition, the safety valve 11 operates when it falls down in all directions.

Next, as shown in FIG. 5B, in the second embodiment, instead of the spherical valve 9 in the first embodiment, the annular valve seat 7 of the water stop portion 6 of the discharge pipe 5 is provided. It is characterized in that a water stop valve 31 is provided. Further, since the spherical valve 9 is not used, the recess 8 can be omitted, and there is no need to incline the bottom surface of the water stop portion 6.

As shown in FIG. 5A, the water stop valve 31 is formed of a film-like elastic body separated into a plurality of elastic pieces 32 by slits 33. When a predetermined hydraulic pressure is applied by the air pump 26, the water stop valve 31 is opened by bending each elastic piece 32 toward the discharge port 23 (FIG. 5).
(See the two-dot chain line in (b)).

Therefore, when the pot is inclined toward the discharge port 23 and the liquid pressure of the liquid to be leaked is smaller than the predetermined liquid pressure, the elastic piece 32 does not bend, and Can be prevented.

If the above-mentioned predetermined hydraulic pressure is set to an excessively high pressure, the water shut-off valve 3 can be operated even if the air pump 26 is pushed in.
1 is not opened, so that the water shutoff valve 31 is appropriately set to be opened at a low hydraulic pressure slightly higher than the hydraulic pressure of the hot water leakage when the pot is inclined to the discharge port 23 side.

As shown in FIG. 6, the third embodiment is characterized in that a water stop valve 34 for opening and closing the communication port 10 is provided in place of the spherical valve 9 in the first embodiment. There is.

The water stop valve 34 is attached to the lower end of a spring 35, and the upper end of the spring 35 is fixed to a mounting portion 36 on the upper inner surface of the discharge pipe 5.
Is urged downward to close the communication port 10. Water stop valve 31
When a predetermined hydraulic pressure is applied by the air pump 26, the water stop valve 34 is pressed upward to open the communication port 10 (see a two-dot chain line in FIG. 6).

Accordingly, when the pot is inclined toward the discharge port 23, if the liquid pressure of the liquid to be leaked is smaller than the predetermined liquid pressure, the communication port 10 is closed by the water stop valve 34. Therefore, leakage of hot water can be prevented.

In the same manner as in the second embodiment, the water shut-off valve is set at a low hydraulic pressure that is slightly higher than the hydraulic pressure of the hot water leak when the pot A is inclined to the discharge port 23 side, as in the second embodiment. 34 is set appropriately so as to open.

[0034]

As described above, according to the present invention, the water shutoff portion is provided in the liquid passage close to the discharge port, so that when the pot is inclined to the discharge port side, it is possible to prevent hot water from leaking from the discharge port. Can be prevented.

In addition, since a safety valve device is provided in the liquid passage in addition to the water stop portion, when the pot is inclined to the discharge port side,
In the same manner as described above, hot water leakage can be prevented by the water stopping portion, and when the pot falls, the safety valve device operates to close the liquid passage, so that the effect of preventing hot water leakage can be further enhanced.
